  • Page 8: General Information

    GENERAL INFORMATION Introduction The EHS is a high speed, high vacuum, high capacity, hospital grade sterilizer with FDA cleared flash cycle. A built in vacuum pump and steam generator allows for increased load size and dramatically reduces total cycle time. The closed door drying system provides a faster and more thorough drying cycle.
  • Page 9 The Jacketed chamber: This autoclave has a jacketed stainless steel chamber. The space between the walls of the chamber and jacket is used to generate and provide the steam required by the autoclave. The heating elements are located inside this cavity as is the mineral free water supplied by the reservoir.

  • Page 44 For Unwrapped Cycles: Note: Trays need not be removed for unwrapped cycles. Before placing a dental handpiece onto a sterilizer tray, make sure that the instruments that are not of the same metal (stainless steel, carbon steel, etc.) are separated and placed in different trays. In case carbon steel instruments are used with stainless steel trays, the tray should be lined with a towel or paper-wrap before positioning the instrument.
